This type of Bearing are widely used in heavy industries like Steel Plants for conveyor system. Main
advantage is within a given space double row will take maximum radial load. Generally they have
one double cup (outer race) and two cones (inner race).

To achieve the required radial and axial clearance a spacer is provided in the factory, selectively for
each bearing before final assembly.

By this arrangement assembly in the user shop floor is made much easier. Nut can be fully tightened
and locked. No fine adjustment, taking back by 1/6 turn or torque loading are necessary.

No separate provision is required to take thrust load. Radial as well as axial clearance can be either
widened or narrowed depending on the end use requirement like :

The Bearing and chock assembly can be removed from the next as a unit without loss or
condemnation of lubricant. The chock assembly can be re-installed on another roll neck in a
minimum of time. The space limitations on medium duty installations have made it necessary to
provide narrow double row Taper Roller Bearings, thereby the bearings become cheaper in cost.

Applications where high load capacity in a minimum of width required, double row Taper Roller
Bearings have been popular. In high speed applications like rolling mills subject to medium
separating forces, double row Taper Roller Bearings with taper bore can be used. Assembly of two
row Taper Roller Bearing is very easy. No pre-loading is necessary. It is a simplified design
eliminating cumbersome construction and extra thrust devices.
